' ANGLE-COCK non RAILWAY-CARS.

Specification of Letters Patent.

Patented :June 1909.

Application filed March 5, 1909. Serial No. 481,491.,

citizen of the United States, residing at the city of St. Louis, in theState of Missouri,

have invented a certain new and useful Angle-Cock for Railway-Car's, ofwhich the following is such a full, clear, and exact de-- scription aswill enable any one skilled in the art to whichit appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this speci- .fication.

The angle cocks of air brake pipes on railway cars are connected by hosepipes pro vided with'couplerswhich automatically release when the hosepipes are brought into horizontal osition by the separation of the cars.The rakemen, therefore,d0 not, as a usual thing, uncouple the hose pipeswhen two cars are uncoupled. These couplings, however, often fail toautomatically release and the result is that either-the hose pipes arebroken or the angle cocks are pulled from the cars and lost. In order toprevent the entire air brake pipe from being disarranged when thisoccurs, a very slight connection is made between the angle cock and themain train pipe. The difliculty of loosing the angle cocks has beenheretofore overcome by providing an angle cock holder made sepa ratefrom the angle cock itself and engaging .either with the head of theangle cook or with thehead of the angle cock and the adj ac ent. airbrake pipe. There are two objections to such holders,howcver: First, theholders add considerably to the cost of the angle cock equipment, andsecond, as it is not practicable to machine them, they do not fit theangle cocks accurately and consequently the angle cocks are allowed tomove so that the slight joint above referred to is'often worked loose sothat the air escapes and the brake system is renderedinadequate.

- The object of my invention is to provide an angle cock for railwaycars to overcome the abovedifficulties' and this I accomplish by formingintegral with the angle cook a lug or plate by means of whichit may berigidly secured to the railway car. 1

In the accompanying drawings which illus trate two forms of .angle cockmade inaccordance with my invention, Figure 1 1s a side view on areduced shale, showing a ortion of two railway cars, together with teir,v r

train pipes, hose pipes and angle cock con- -angle cocks 10 is an airpipe 11,.

nections Fig- 2 is a view of one of the angle cocks Fig. 3 is aside'view and Fig. 4 is a section on the line 44'-of Fig. 3.. Fig. 5 isa view similar to Fig. 4 but showing a slight modification. i

Like marks of reference refer to similar partsin the several views ofthe drawings;

10 represents the angle cocks which may be of any usual form. Secured'toeach of the This pi' e 11 is connected with the train pipe 12 y means ofa sleeve 13. This sleeve 13 only engages slightly with the pipes 11 and12, as shown in Figs; 1 and 5, so that the pipe 12 will not be pulledfrom the car in case the angle cock becomes detached for the reasonsabove stated.

14 represents the dead-wood of the rail} Way car. In order to secure theangle cock 10 to the dead-wood 14, or any other suit able portion of thecar, I provide it witha' lug or plate 15 which is formed'integral withit'but preferably with its hexagonal head 16. The lug or plate 15 isprovided with bolt holes 17 through which pass bolts 18 which so: secureit to the dead-wood 14.

In Fig. 5 I have shown a slight'modification to adapt the angle cock tobe secured to a car in which the dead-wood '14 is turned with itsflanges projecting forward. In this case I provide a lug or plate 19which, like the lug 15, is formed integral with the hexagonal head ofthe cook, but which first projects upwardly,.after which, however, it isturned over rearwardly so asto engage with the upper sideof'the flange20 of the deadwood 14 and is secured in position by means of the bolts18 in a manner similar to the lug or late 15 heretofore described.

t will be seen that, by my construction,

a means is provided for securing the angle cock in position-to preventits loss without the use of a separate holder and at the same time it issecured to the car much more rigidly than is practicable with theseparate 10( holder and consequently the joint betweenthe pipes-"'11 and12 is not likely to become loosened so as to allow the escape of air andinterfere with the proper working of the brake system.

Having fully described my invention, What I claim as new and'desire tosecure by Letters Patent of theUnited States is:

l. The cornbination with a railway car, of an air brakepipe therefor, anangle cook 11' for seid air hrake pipe, said eagle cock being 4. Thecom'bination with a railway car, 15 rovlded W1th an integral lug Forsecuring of an air hrake ipe therefor, an angle cock;

1t to said can. for said bra e pipe, and a lug formed en air brake pipetherefor, an angle cool; or

2. The combination with a railway car, ietegral with said ang e sock andprojecting of an air brake pipe therefor, and an angle upwardly and"then reerwardly therefrom, cock for said an brake pipe, said angle cockl havingea lug formed integral with its head securing it to saidgeer.for securing i? to said car. in testimony whereof I have hereunto set 3.The combination with a railway ear, of I my hand and afiixe'd my seal inthe presence f l of the two subscribing witnesses.
